This project is designing AutoMatrix, a traffic congestion simulation platform for large-scale traffic modeling, routing and congestion management. AutoMatrix is currently capable of simulating over 16 million vehicles on any US street map and executing traffic estimation, prediction and route assignment algorithms with high-throughput. This research has the potential to extend real-time scheduling on massively parallel Graphics Processor Unit (GPU) architectures to attack a variety of data-driven, interactive and dynamical algorithms with timely operation.
